0 Student satisfaction win the middle school calina Method A: Survey 40 students in to seventh grade math cases
72 percent are satisfied with the food in the cafeteria
Nethod B Survey 65 students from a list of all students in the school
85 percent are satisfied with the food in the catetera

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)

it is 10.6 according to my calculations
